CN5611 from ShangHai Consonance Elec, in a SOT-89-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive supply input, 2.7V to 6V. Also powers the internal control circuitry. Absolute maximum pin voltage -0.3V to 6.5V. |
| 2 | GND | power_in | Ground / power return. Should be tied to a large copper pour for thermal dissipation. |
| 3 | LED | output | LED cathode connection. Internal power transistor sinks the regulated constant current (up to 800mA) from the LED cathode to GND. Dropout voltage ~135mV at 200mA, ~410mV at 700mA. |
| 4 | ISET | input | Constant LED current setting pin. Connect a resistor R_ISET between ISET and VDD; I_LED = 910V / R_ISET (e.g. 4.55kΩ sets 200mA). 1% metal-film resistor recommended. |
| 5 | NC | unconnected | No internal connection. Leave floating or tie to GND. |
